A replica of this. The M49 in these cars are a thing of beauty (430hp from 3.5L I6) so i wouldn't touch it, the M30 in road going versions though aren't that great. But it needs serious chassis work. The chassis get flexed even by the stock 200hp if you treat it bad. a +500HP V10 would do that in a sec.

Purely hypothetical thread. I think with the S85 being off the market now we will see more and more interesting swaps utilizing it.

I have toyed with the idea many times. Conclusion was that in NA form they are limited to around 500whp which in this day and age is not really that exciting. If I had to choose though it would be in a E30 M3 body which we didn't get in South Africa
